1. In a bowl, cream together cream cheese, sugar, margarine, and peanut butter; mix until lumps are gone.

2. Pour mixture into your graham cracker crust and even it out.

3. In a small pot, melt chocolate chips over low heat drizzle the chocolate on the mixture. OR, place chocolate chips in a ziplock bag and place it inside a bowl, then pour boiling water in the bowl to melt the chocolate chips. Once melted cut a small hole on one corner of the bag. Use it to squeeze out chocolate across cake.
